Abstract
An antenna device for a Mobile Phone is disclosed, wherein a distance between a miniaturized radiator and a miniaturized reflector may be shortened by means of an introduced dielectric material optimizing the electrical distance between the radiator and reflector to create a compact antenna unit having a desired cardioid shaped radiation pattern. Furthermore an additional field reducing means in the form of metallic strips is used, for example utilizing an additional dielectric layer, with at least two thin isolated metallic strips running parallel to the current edges of the reflector element to thereby form chokes at the back of the reflector, which is normally directed towards the user, to further concentrate the near-field on this side to an area in between the chokes.
